The MOTU 1248 – Thunderbolt and USB Audio Interface With AVB Networking and DSP (32×34, 4 Mic) is designed for studio recording, installed sound, and live sound reinforcement applications such as mixing a band in a club or music venue. The 1U 19″ rackmountable device features four balanced microphone inputs with individually switchable +48V phantom power, two dedicated hi-Z guitar inputs, 8 x 12 balanced analog with separate main and monitor outs, 2 x 8-channel ADAT optical, and RCA S/PDIF (with sample rate conversion), for a total of 32 inputs and 34 outputs. Additional I/O can be added to the system through AVB networking.

The audio interface utilizes ESS Sabre32 Ultra converters to provide a dynamic range of 123 dB (A-weighted 20 to 20,000 Hz) on balanced TRS analog outputs, a THD+N rating of -110 dB, and a total system latency of 32 samples (0.66 ms) while recording at up to 24-bit 192 kHz resolution. A front panel backlit 324 x 24 LCD provides detailed metering for all analog and digital I/O as well as provide a GUI for adjusting hardware settings.

Using Thunderbolt connectivity, the audio interface can stream 128 audio channels in and 128 channels out to the interface’s physical outputs, the DSP-powered 48 digital routing matrix, or AVB audio network streams. The interface can also use high speed USB 2.0 (3.0 compatible) using class compliant drivers to work with most digital audio workstations.

The MOTU 1248 is a 48-channel digital mixer it can mix physical inputs on the interface, audio channels from your host computer software, AVB audio network streams, or mixer outputs. It features seven stereo auxiliary busses, three groups, a reverb bus that can serve as an alternate 4th group, a main mix bus, and a separate monitor bus that can function as a solo buss.
